LOCK.

Specification of Letters Patent.

Patented Sept. 7,1915.

Application filed June 4, 1915. Serial No. 32,109.

To all whom it may concern: I

Be it known that I, HENRY G. Vorenr, of the town of New Britain, county of Hartford, and State of Connecticut, have invent at a point on the outside escutcheon, the position of the outside bolt in a two-bolt lock of the general type illustrated in Letters Patent No. 898,434, granted to Sargent &. Company, on September 15, 1908, as assignee of William J. Carroll. Nevertheless, certain features of my improvements may be used to advantage in other applications or connections.

The primary object of the invention is to provide simple, efiective mechanism for translating the movements of the bolt into corresponding movements, in a direction depth-wise of the door, of an indicating member or plunger associated with the outside escutcheon.

To this and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a fragmentary outside elevation of a door equipped with an indicator lock embodying my invention, showing the bolt in its retracted position; Fig. 2 is a similar view, showing the bolt in its protracted position; Fig. 3 is a section on line 33 of Fig. 1, looking to the right; Fig. 4 is a section on line 4-4 of Fig. 2, looking to the left; and Fig. 5 is a rear face view of that portion of the escutcheon which carries the indicator.

Referring to thedrawing, the door 10 is shown equipped with a mortise lock 11 having a dead bolt 12. This lock is not shown in detail, but the bolt 12 may be the outside bolt of a two-bolt lock constructed in accordance with Patent No. 898,434 mentioned above. vided with a keyhole 14 for the insertion The outside escutcheon 13 is pro into the keyhole 15 of the lock case of a key adapted to operate the bolt 12 in the usual manner. Mounted on the outside escutcheon 13 at a point adjacent the bolt 12 is a bushing or housing 16 which may be constituted by a sleeve appropriately secured to the escutcheon at the inner face of the latter. The bushing or sleeve is provided with a large bore 17 at the rear part adapted to receive the body portion 18 of an indicating member or plunger 19, the forward end of which is ofsomewhat reduced diameter, and fits a smaller bore 20 communicating with the bore 17. The junction of the body portion 18 of the plunger with the reduced head portion forms a shoulder adapted to limit the forward movement of the plunger relative to the escutcheon, as will be understood. A pin 21 driven into the side wall of the bore 17 fits an inclined groove 22 in the body portion of the plunger in such a manner that as the plunger is turned on its axis it will be advanced or retracted in the bushing. Thus the plunger has a screw movement in the escutcheon.

The turning movement of the plunger is imparted to the same by means of a sliding member 23. This sliding member is preferably in the form of a platecarried by the bushing, and in the present instance it is slidably secured to the bushing by means of small screws 24 passing through longitudinal slots 25 in the plate, and into threaded holes in the rim of the bushing, as shown in Fig. 5. Between the slots 25, the plate 23 is provided with a small transverse notch 26 engaging a pin 27 extending from the rear face of the plunger and eccentrically mounted on the plunger. By this means, the plunger is turned on its axis, and thereby advanced or retracted, as the slide 23 is moved in one or the other direction on the bushing. The slide is operated in a suitable manner from the bolt 12, and in the form shown, the tumbler stump 28 on the bolt carries a pin 29 which extends through a clearance slot 30 in the lock case and engages a transverse notch 31 in the plunger actuating slide. The operation of the device will be obvious for the most part from the foregoing description. In the particular form shown, the plunger is retracted from the escutcheon when the bolt is in the retracted position. Thus a chamber-maid or any one familiar 25 tracted position of the bolt, as an obvious -reversalof'this arrangement would bewithwith the general working of the indicator will know that the'bolt is retracted as soon aslit is determined that the plunger is re-.

T'tracted which can be done either visually or by running the finger over the end of the bushing; As the bolt is protracted by the key, the pin '29v Will move with the bolt in a1] straight line, and will shift the slide 23 in such a direction as fto move theplunger out 1n the bushlng until its end face. 1s substantially flush with the outer face of the escutcheon.
